changing batery location
Anyone out there consider moving the battery to a more accessible location (1930 Tudor)...such as under the hood? Ideas...anyone?
Also...based on a recent roadside ignition failure apparently caused by the add-on fuse at the starter motor...all power went out to all lights when that 10 amp fused failed. Not great for safety if that happened when it is dark ...no blinkers or lights of any kind worked. Considering adding a discreet 4-6 fuse box to the car to keep lights working even when the fuse on the starter fails. Suggestions? Location? Is there a reason why that fuse is on the starter instead of anywhere else? Should I simply (probably a bad word choice) eliminate the starter fuse and wire the battery main wire (negative) to the fuse box with a fuse for the starter...or is a fuse for the starter even necessary as it does not protect the starter itself? That fuse shuts down everything except the starter...including the ignition coil...so even though the starter turns there can be no spark. Sorry for so many questions and using all of the expertise on this site as a crutch. I am a newbie to pre-war classics. Last edited by German guy; 10-11-2023 at 02:49 AM. |

Re: changing batery location
Some have added a fuse box. The starter would be fed directly by the standard cable from the battery and a 12 AWG wire from the starter could feed the new fuse box.
To convert US AWG wire sizes, this can be used: https://www.rapidtables.com/calc/wire/awg-to-mm.html |

Re: changing batery location
Hey, thanks a lot for the quick reply. Makes sense. I will probably run the wire straight up the firewall from the starter to the fuse box. I found a pretty nifty very small..low profile fuse box that flashes an LED to ID the blown fuse. It holds 6 of the modern mini-fuses...which are far more available here than the old glass models. As I am adding fuses, I am exiting the ethereal realm of "authentic" anyway. My goal is to get everything up to standard in time to drive it to Epernay (Champagne), France in March '24. 315km which normally takes me 3.5 hours but with the "A" will probably take 8 or more since I will stay off of highways and pass through every tiny village. 8 hours at one go seems a bit much for my 93 year old toy. Should be a great drive if I can develop enough confidence in the car's reliability. I might add a precautionary overnight close to the halfway point and visit the Bugatti factory and museum.
Thanks again for the assist. Last edited by German guy; 10-11-2023 at 05:58 AM. |

Re: changing batery location
Keep the battery where it is and use a maintenance free battery. Use a 30 amp circuit breaker instead of the fuse. Add a fuse box to run accessories including lights. Marine supply houses have very nice fuse boxes. Mount the fuse box on the engine side of the firewall with a magnet so you don't have to drill any holes. Keep the wiring neat and tidy and label the fuses.
While I was typing you responded with a neat fuse box. I like that it has LED indicators.

Re: changing batery location
I recently bought a slant cab and the battery was mounted on top of the rear bumpers, with a board running across.
I was going to put it back in its reg stay, but the cables were miles long. My pass runningbd had some rot towards the rear, so I swung the cables up through the runningboard and mounted the battery there. I plan on putting a nice box over the batt. Since I have a spare set of new boards, I saw no harm in doing this with the damaged board. I must say I love the accessibility. |

Re: changing batery location
The Optima battery is smaller and can even be mounted on its side opening up many possibilities.

Re: changing batery location
Another option is to leave the battery under the floor but install this kit https://www.snydersantiqueauto.com/p...7804&cat=41699 that allows you to remove half the floor board.
Most run a 30 amps fuse in the holder, not 10 amps. I also have a hidden fuse box under the gas tank that bolts to the back side of the junction box to protect my accessories (turn signals, Sport Light, fog lights, wipers, ignition, etc.). The headlight circut has it's own 20amp circuit breaker. Last edited by Y-Blockhead; 10-13-2023 at 05:21 PM. |

Re: changing batery location
I also run a 30 amp fuse. It has blown when I had a short circuit in the headlight circuit, so I know it does work.

Re: changing batery location
When I look under the hood of a Model A there are two things I hate to see. The first is a battery and the second is an alternator, but that is just me.

Let me add a third one. My car has a pressure radiator and the guy hung one of those $3 plastic tanks on the firewall. I bought one of the stainless ones and painted it black to help hide it. I had to stick with the plastic fan due to no clearance for the 2 blade aluminum I had bought. |

Re: changing batery location

Re: changing batery location
I think that back in the days of Model A's being utilitarian vehicles, like late 40's and 50"s, relocating batteries to the firewall was common. my 31 coupe has a nice line of rust pits across the left side of the firewall where a battery once resided.

Re: changing batery location
I use Optima Batteries. I install them under the floorboards and forget about them for the next 10 years or more.
Personally, I would not have a battery hung on the firewall, but this is just my opinion. Chris W. |

There they go again talking about the floor board on the passenger side. The battery is on the passenger side! Why they don't refer to right and left side, I don't know. Can be quite confusing at times.

Re: changing batery location
Starboard and Port. Right and left depends on whether you are inside looking forward or outside looking at the front of the car. Starboard and Port stays with the car (or boat) and right and left stays with the observer.

Re: changing batery location
I've been happy with my Optima mounted flat in the original location for 3 trouble free years now. It fits just right in the frame rail.
